ONTAP compares pointer information in the Snapshot copy with data on disk to reconstruct the missing or damaged object, without downtime or a significant performance cost. The policy specifies when to create the Snapshot copies, how many copies to retain, and how to label them. This Snapshot copy is currently used as a reference Snapshot copy by one or more SnapMirror relationships.
